NoN-nErILLAnLE nor'rLE.

To all whom it may concern Be it known that I, GEORGE J AMES VVELoI-I,

subject ofthe King of Great Britain, residing at Wanganunin the Dominion of New Zealand, have invented a new and useful Improvement in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to that class of bottle in which provision is made against the re-filling of the bottle in order thus to prevent the fraudulent use of an empty bottle.

The invention consists in a special form of neck and of a special typeof stopper inclosed within the neck and by the uselof which freedom is obtained for thepouring out of the bottles contents while a block is afforded against the entry of liquid through the neck into the bottle. This stopper is shaped to fitinto and seal a tapering portion of the bottles neck and 1s inclosed within a chamber formed in the neck and adapted to allow of a limited amount of vertical movement to the stopper. The stopper is also formed with a top surface such as to concentrate any inilowing liquid on to it so as to force it back on to its seat in the neck. This top surface is also preferably so formed that when an attempt is made to force liquid through the neck a whirling motion will be communicated to the stopper that will cause it to more tightly 3am on to 1ts seat in the bottle neck.

in full describin the invention refera;

ence will be made to the accompanying sheet of drawings, in which Figure l is a sectional elevation of the bottle neck with the stopper in position therein and shown in elevation. Fig. 2 is a plan of the stopper. Fig. 3 is a sectional elevation thereof. Fig. 4: is a sectional eleration of an alternative construction of the bottle neck.

The bottle neck a is formed as shown in Fig. 1 with sides tapering upward and out ward from the body Z) and then carried sharply inward to form a ledge c having a constricted outlet opening d therein. The neck is then widened again to receive a sealing cork e that may be covered by a layer of sealing wax or the like A chamber g is thus formed in the neck such chamher having sides tapering inward toward Specification of Letters Patent.

the bottom. The" inside wall of the chamber g is made with its lower portion constricted to a lesser diameter than its upper portion so as thereby to form a slight ledge it all around it. The stopper j is also made of the shape shown in the drawings andis formed hollow so that it will be capable oi floatmg in a liquid. The outer diameter of the stopper is tapered to correspond with the tapering in the wall ofthe chamber 9 audit, too is formed with its upper por tion of enlarged diameter to its lower portion so as toconstitute a shoulder 70 thereon.

The upper portion of the stopper is adapted to fitinto the upper portion of the chamber and its lower portion into the lower portion of the chamber and the shoulder 70 is so situated that when the stopper is right down, a space m will be inclosed between ,ment is suflicient to permit of a space being left between the stopper and the chamber wall through which the liquid may pass from the bottle when the neck is inverted and the stopper drops. The top of the stopper is formed with upwardly projecting lugs a which engage with the ledge 0 1n the neck and thereby provide the necessary passage for the liquid to escape around the side of the stopper along between the ledge c and the stopper top and out through the orifice d.

The upper surface of the stopper is made in the shape shown in the drawings, that is with a pair of inclined faces 0 extending around it from radially opposite points and inclining downward in opposite circumferential directions. These surfaces also dip toward the center of the stopper. Each inclined surface at the bottom of its incline joins with the surface of oneof the projections at which is then given an upward 1nclination in the manner shown. The forcing of liquid into thenec'k will therebyengage with these inclined faces and cause the stopper to turn around andjam itself into its seat in the chamber to close the neck passage.

at its bottom shown in Fig. 1. Any attempt to refill the bottle by allowing liquid to flow in will cause the stopper to be carried back on to its seat and the passage thereby becomes sealed.

The stopper will be inclosed in the chamber g during the blowing of the bottle in the well known manner'and for the initial filling of the bottle it will be held up in the chamber by means ot-a fin e wire passed through a small eye .29 made in the bottom of the stopper and carried out through the neck. hen the bottle has been filled, the wire is withdraw-n thereby permitting the stopper freedom .to act in the manner required for the purpose oi the invention.

Instead of the-ledge 0 being made integrally with the bottle neck a as shown in Fig. 1, it may be made as a disk-that fits into the neck as shown in Fig. &. It is then held in place therein against any withdrawal by means of the spring catches T which en- 5 gage with the groove 8 in the internal periphery of the neck in a manner already well known. This manner of constructing the apparatus will permit of the stopper j being placed in the bottle after filling and for the disk then being inserted to lock the stopper in the neck in the required manner.

IV hat I do claim as my invention, and desire to secure by Letters Patent is In non-refillable bottles, a neck for the bottle formed with a constricted portion and a chamber beneath such portion having sides inclining inward toward the bottom end and formed with a ledge part way down its inclined side, and a stopper inclosed within, the chamber and capable of limited vertical movement therein such stopper being formed with tapering sides having a shoulder there- Gopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
